if( $_SESSION["logging"])
{
print_secure_content();
}
else {

You have to keep the session_start(), before you echo or output . You have these HTML which outputs before session_start() runs.
Your solution:
<?php
/* Make sure this part is at the top */
error_reporting(E_ALL & ~E_NOTICE);
session_start();
?>
<!-- Now other -->
<form action="index.php" method=get>
<h1 align="center" style="color:gray" >Welcome to this simple application</h1>
<?php
if( $_SESSION["logging"])
{
print_secure_content();
}
else {
if(!$_SESSION["logging"])
{
$_SESSION["logging"]=true;
loginform();
}
?>
